“…Chronic-contained rupture of aortic aneurysm was first described by Szilagyi et al 2 and Galessiere et al 3 Since the initial description, less than 100 similar cases have been documented worldwide. 4 Its presentation is distinctly different from that of acute rupture of aortic aneurysm.…”

“… 5 Booth and Galland 7 reported that the clinical features of contained AAA rupture are vague with back pain in 64% of cases, abdominal pain in 20%, groin pain in 14%, femoral neuropathy in 8%, sepsis in 10%, and asymptomatic in 8%. 4 The clinical presentation may masquerade as metastatic carcinoma, infectious spondylitis, retroperitoneal infection, psoas abscess, and, rarely, obstructive jaundice. 8 The mechanism of chronically contained AAA rupture is not clear.…”

Chronic-contained rupture of an aortic aneurysm is a rare subset of ruptured aneurysms. The presentation is unusual, and the diagnosis is frequently delayed. Here, we describe a case of contained rupture of abdominal aortic aneurysm that presented with signs and symptoms of femoral neuropathy. Clinical and radiological findings were initially misinterpreted. The correct diagnosis was formulated belatedly, causing a progressively increased risk of fatal events. Surgical aortic repair was performed and the postoperative course was uneventful. In conclusion, in the presence of a retroperitoneal mass, a diagnosis of chronic-contained rupture of an abdominal aortic aneurysm should be considered.

“…In the future, we expect to further enrich the variability of the training data by improving the physical models or collecting more patient data to incorporate the marginal situations. Specifically, we generate a large amount of data by varying three parameters in the computational G&R simulations, which may not be enough to capture all the different features in actual AAA evolution, e.g., intraluminal thrombus [50,52,53], other morphological parameters [54,55], and influence of surrounding tissues [56,57]. Hence, more parameters and more complex models will be carefully selected in the future to provide better simulation-based training data.…”

A Deep Learning Approach to Predict Abdominal Aortic Aneurysm Expansion Using Longitudinal Data

An abdominal aortic aneurysm (AAA) is a gradual enlargement of the aorta that can cause a life-threatening event when a rupture occurs. Aneurysmal geometry has been proved to be a critical factor in determining when to surgically treat AAAs, but, it is challenging to predict the patient-specific evolution of an AAA with biomechanical or statistical models. The recent success of deep learning in biomedical engineering shows promise for predictive medicine. However, a deep learning model requires a large dataset, which limits its application to the prediction of the patient-specific AAA expansion. In order to cope with the limited medical follow-up dataset of AAAs, a novel technique combining a physical computational model with a deep learning model is introduced to predict the evolution of AAAs. First, a vascular Growth and Remodeling (G&R) computational model, which is able to capture the variations of actual patient AAA geometries, is employed to generate a limited in silico dataset. Second, the Probabilistic Collocation Method (PCM) is employed to reproduce a large in silico dataset by approximating the G&R simulation outputs. A Deep Belief Network (DBN) is then trained to provide fast predictions of patient-specific AAA expansion, using both in silico data and patients' follow-up data. Follow-up Computer Tomography (CT) scan images from 20 patients are employed to demonstrate the effectiveness and the feasibility of the proposed model. The test results show that the DBN is able to predict the enlargements of AAAs with an average relative error of 3.1%, which outperforms the classical mixed-effect model by 65%.

“…A CCR-AAA is a well-known, extremely rare subtype of AAA that was first reported by Szilagyi et al in 1961 [1–3]. It is characterized by low blood loss and stable hemodynamics, which are due to hemostasis by tissue peripheral to the retroperitoneum when the aortic aneurysm ruptures [4, 5].…”

Chronic contained rupture of abdominal aortic aneurism complicated with aortic occlusion: a case report

et al. 2019

Background Chronic contained rupture is a subtype of an abdominal aortic aneurysm rupture. Its diagnosis is sometimes difficult due to lack of typical symptoms. We would like to report the challenge of diagnosing chronic contained rupture of abdominal aortic aneurysm with a retroperitoneal tumor. Case presentation A 60-year-old man reported perceived lower abdominal pain 7 months earlier that spontaneously remitted. A contrast-enhanced computed tomography (CT) indicated an abdominal aortic aneurysm and a mass lesion surrounding the abdominal aorta and iliac arteries. Fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET) showed an increased accumulation of FDG in the margin of the lesion, indicating a retroperitoneal tumor. A CT-guided biopsy revealed only retroperitoneal fibrous tissue with chronic inflammation. We were thus unable to reach a definitive diagnosis. At 1 month after the initial examination, intermittent claudication was newly observed. A follow-up contrast-enhanced CT scan revealed abdominal aortic occlusion. Mass resection and bypass surgery were performed for diagnosis and treatment. Intraoperative and pathological findings led to the diagnosis of chronic contained rupture of an abdominal aortic aneurysm. The patient was discharged 19 days after surgery. Conclusion The mass peripheral to the abdominal aorta should be considered the possibility not only of tumor but also of chronic contained rupture of an abdominal aortic aneurysm.
